Question How-to share internet connection through router

I have a Telstra 3G Wireless Modem that I've setup on my desktop computer. Also connected to my desktop (via ethernet) is a Netgear DG834G router. Connected to this router (wirelessly) are two laptops.

I'd like these laptops to be able to connect to the internet via the 3G modem. I figure the way it'd work is through the router, since all computers are connected to it. What I need to work out is how to share the 3G modem connection through the router to the other two laptops...

Any idea how I would do this?

You didnít say if the router has an Internet connection. If it doesnít and is being used essentially as an access point, then make sure itís DHCP server is disabled and then set up Internet Connection Sharing (ICS) on the PC with the 3G modem attached. Other PCs then need to be set up as clients of the ICS PC.

If the router does have an Internet connection and is being used as a router then that complicates things significantly.

Sorry, yes, the router has an internet connection (username and password entered in setup), but when I was testing the 3G modem, I unplugged the phone line from the router so as not to confuse myself which the different connections.

The problem is that to share the 3G connection the PC that uses that interface needs to run ICS. I think 3G devices appear as dial-up type connections in Network Connections and you can’t simply bridge it with an Ethernet or wireless connection. With ICS the PC is effectively set up as a router and it will be a DHCP server to other computers on the Network. Since your Netgear router is also a DHCP server / Internet gateway this will lead to conflicts. So basically I think you can only share the 3G device if you set up the Netgear router as an access point with the 3G PC operating ICS.

There are a number of newer routers these days that have the option to plug in a 3G modem as a second / reversionary Internet device.

not use if the ICS from your PC is your choice but you can NOT rely DG unit to do any of 3G connection

1. 3G-PC-ICS connection -DG device setup as access point

or

2 Buy correct 3G modem

Thanks for the replies!

Buying a proper modem isn't really an option as I'm only needing this for a few days while our phone lines are down (and hence no internet).

I know that ICS stands for 'Internet Connection Sharing', but when to say 'run ICS' do you just mean to right-click on the connection and enable sharing, or is it something different you're referring to?

I'll have to research some tutorials for setting up the DG834G as an access point and try that...

I finally got it.

I am using a netgear wireless card in my c2d desktop with another nic card.


BTW i am using win7

i let the 3g usb modem connect first. in the network connections, i opened the usb's network connection and in ipv4 tcp ip setting, i added the ip address of my belkin modem in which i had disabled dhcp as an add new dns.

It let me through.

I connected my notebook via wifi to the belkin, and voilla, i got internet through to the notebook computer as well.

Now i will try connecting my pda and my wifes iphone, and see how it all works.
